Updated from Xubuntu 8.04 to Ubuntu 8.10. Looks really good. However, I had quite a few problems with pulseaudio and ekiga, and eventually ended up removing pulseaudio from the system.
On a related note, I am troubled at the apparent hatred of many aspects of Canonical and Ubuntu, as though their offering was some right or natural state of being. Clearly Ubuntu has done a lot right, and equally clearly some people seem to resent some aspect of this, or see some fearful negative hidden to the rest of us.
I remain grateful for the entire ecosystem that results in work like Ubuntu, and for the freedoms it seems to me it still allows better than most corporate-backed options. It distresses me that we see such negative polarisation.
